New Pump And Expansion Tanks
October 1, 2006
A.O. Smith has an all-new line of ProMax® Pump and Expansion Tanks that feature a metal air valve, multiple head construction for added structural strength, and a positive lock retention system for controlled compression in the diaphragm, eliminating the loss of air or water leaks. The powder-coated tank exterior provides maximum resistance to UV sunlight and resists corrosion.
